I just tried a Tokina 11-16 on a BMCC EF and it would not focus to infinity. A Rokinon 35mm focused properly, but as we didn't have another Tokina to try, it was not clear whether the problem was this particular lens or all 11-16 Tokina's.

I know it doesn't autofocus, but I was thinking they might be focusing through the camera or LANC remote. Something like that. But what's happening is a manual pull of focus ring on lens to infinity is not sharp to infinity within camera recording?? Right?

Focused manually. I really want to test another lens now because of the whole thing where some Tokinas are just duds and others are great. Or maybe I'm just being picky. It is rather unsatisfying though when you see something tack sharp at 16 and then zoom out to 11 and its just slightly off. The 11 focuses closer fine, but yeah infinity at least on my lens and the OP's lens is no good.

I have a lens that goes past infinity...you have to bring it back a touch to get sharp focus at infinity. I don't like it but can at least work with it. Are you saying that it is impossible to get sharp focus at infinity with the Tokina?

It's pretty bad at 11 wide open while concentrating on the windows of the building in the background- I keep asking myself if this is normal for this lens or if it's a dud, but I'm pretty sure mine is a dud.

Shame - it's pretty nice at 16.

This is also a pretty good view of what some wides look like on the camera. I was about 12-15 ft away from those flag poles in the foreground.

I was planning to get one because of all the great reviews I'd read about it. It's reasonably fast, pretty good build quality, and a reasonable cost.

I'd talked with Matthew Duclos and was planning on having them do a cine-mod.

While on the BMCC it wouldn't be super wide, I'd heard it would do a pretty good job on the wide front until I can afford a set of primes. Likely by the time I can afford a set primes, like the cp2's, there will be a entirely new set of camera's out there and the sensor size will be different.

Wondering if this is just an an instance of a few bad lenses or a problem with the ability of the lens in whole.

Hoping that Tokina is paying attention or maybe Matthew will chime in.

I heard it was good from a ton of people and considering Duclos made a cine version of it made it seem like it was worthy of its not that expensive pricetag.

There's not all that much out there for EF mount lenses that are aspherical wides that are also fast and also sharp.

The sigma and canon 10-20 or whatever they are - are slower right? I don't deny that this is a tough area with the BMCC, but 19mm gets me most of the way there most of the time.

The MFT BMCC will add so many options in this area, so it'll be great when that's out.

And to the poster above - i think it's just my lens is a dud. I heard Tokina's QC isn't that good at all and people get ones with focus issues a bunch. Sometimes on the wide end like mine, sometimes on the 16 end. I guess it's worth the hassle if you eventually end up with a decent wide fast lens.

Matthew spoke highly of the plain-jane version of this lens. Obviously he likes their completely revamped version better.

Bummer that your lens is a dud. I'd love to hear the folks from Tokina check in but guess they don't do that sort of communicating. Wonder if you can send yours back?

Mine was a mark 1 - but i read reviews online I forget where that the improvements in the mark 2 were mostly only in flare control and not sharpness and that one place said his mark 1 was sharper - thinking about getting the mark 2 now just to see

Yes, this is true, but the lens body may have been changed slightly as well, as the label colour went from silver to golden.

did anyone try on a canon DSLR body ?I quickly tried my Tokina on a 60 on still mode and I kind of feel same issue ..but I did not checked properly because I am traveling ...will be back In couple of days to proper test it

Hello guysJust tested my Tokina on Canon 7D. I bought it in 2010 and I think it's OK. Take a look below. All focused manually at infinity, RAW, processed in Camera Raw 6.0 with default settings (except for the fill light, which is +50).

Geee, I recently bought the 11-16 for my D7000 and for my future BMCC, but it was so decentred that I sent it back and bought another one just to find out it was all the same. Now i´m glad that they didn´t work when I read this thread.

That's nuts that it's fine on a canon body but slightly off on the blackmagic - that sucks. that's immensely frustrating. and yeah to martin - it seems to be alright on your 7d.

any of the other people that have both the camera and this lens have any luck with it. i also can't believe that other people didn't notice it until now. I guess it's just something with the flange distance with the bmcc or something?

If this can happen with the Tokina 11-16, I'm afraid that may happen with other lens, including Canon's ones…

We really need a database of the EF lens compatibles with the BMC, like this one viewtopic.php?f=2&t=2472#p14489but also specifying if the sharpness at all distance is okay, and the type of mount (EF or MFT + adapter).

maybe I go for the Sigma 8-16mm .. it seems to be a solid sharp lens for the bmcc.. at least in daylight this lens is performing very good.. phillip bloom and marco solario did some nice tests with it.. unfornately not very fast

Went out today with my new Bmcc...at 2.8 no infinity from 11-14mm then good from 15mm.Stopped down was fine at 11mm...but I don't know how far I was stopped down as there was no readout with my firmware, this was a quick test as light was failing but wow.... underexposed footage lifted great when I stopped down.

i bought a NIKON tokina 11-16 and a novoflex adapter with iris control and it works beautifully. it focuses PAST infinity now at both ends, so i have to bring it back, but at least i know I can nail it and it is sharp.

plus it adds manual iris to the camera. it does add $250 to the cost of the lens, but you get a great adapter out of it. nikons focus and zoom backwards though, so be ready for that if you try this setup. not ideal, but better than a soft lense.
